Change some of the driver's functions in order to handle error codes
instead of discarding them. These function now returns 0 on success and
a negative errno value on error.

Avoid discarding called function's returned value. Store it instead in
order to act accordingly.
Update error path to return 0 on success and a negative errno value on
error.

vnt_free_tx_bufs() relies on priv->tx_context elements to be NULL if
they are not initialized (as vnt_free_rx_bufs() does). Add a check to
these elements in order to avoid NULL pointer dereference.

As this is only called twice, just call writel() like a normal driver
should :)
At the same time, clean up the formatting for the irq handler, as there
is no need to have that be incorrect, it just hurts the eyes...

Throughout i2c_driver.c, there are numerous deviations from the two
standards of:
- placing a '*' at the beginning of every line containing a
block comment.
- placing the closing comment marker '*/' on a new line.
Instead, use a block comment style that is more consistent with the
prescribed guidelines.

The probe() function performs a kzalloc to dynamically allocate memory
at runtime. If the allocation succeeds, yet invoking the function
i2c_add_adapter fails, the dynamically allocated memory is never freed.
Change the allocation to use the managed allocation API instead and
remove the manual freeing of the memory in the remove() function.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of new device support, features and cleanups for IIO in the 5.3 cycle
New device support
* mt6577
- add supprot for the mt6765 which requires a few minor additional
new features in the driver.
Yaml binding conversions
* adxl345
* isl29018
* tsl2583
* tsl2772
Minor features and improvements
* ad5758
- declare an of_device_id table rather than just relying on the spi
fallback which doesn't use the manufacturer id.
- drop a set but not used variable left from previous refactor.
* ad7816
- Add a bit more description to kconfig text.
* ad9523
- change calculation order to improve frequency accuracy.
* adxl372
- declare an of_device_id table
* adt7316
- white space.
* at91_adc
- Use dev_get_drvdata directly rather than boucing to the platform device
and back again.
* cros_ec
- add an id sysfs entry to bring in line with the other implementations.
* ds5522
- drop a check on the of_node existing as we don't actually use it for
anything.
* kxsd9
- declare an of_device_id table.
* maxim_thermocouple
- declare an of_device_id table.
* mt6577
- add dt binding entry for mt8183 which is also supported.
* rcar-gyroadc
- tidy up unnecessary error messages.
* stm32-dfsdm
- improved error handling.
* stmpe-adc
- drop an unnecessary variable assignment.
- add an of_device_id table.
- reinit completion on begin converstion to avoid a path in which
previous round had been interrupted, also switch to non interruptible
wait to avoid an issue with a user program using -pg
- simplify interrupt handling by just having them always enabled.
- reset all interrupts on startup and in the timeout handler to
avoid getting stuck.

The vchiq code tends to follow a coding pattern that's not accepted as
per the Linux kernel coding style
We have this:
if (expression != 0)
We want this:
if (expression)
We make an exception if the expression refers to a size, in which case
it's accepted for the sake of clarity.
